Stonemasonry- 5 Sep 2026
Really pleased with the work carried out on our property, the two fellas were fantastic from start to finish and worked really well as a team. John came up with some really innovative solutions that only someone with an extensive experience in stonemasonry skills would do, and the finished result looks great. The work was completed quickly, efficiently and, importantly, at a very fair price. Both were friendly, professional and clearly took pride in their work. We would have absolutely no hesitation in recommending them to anyone looking for similar work. We may well be getting back in touch ourselves for some further work in the future!
